Modern solutions for a sound fuel system

The reduction of emissions in passenger cars dominates public discourse, and there is increasing demand for the use of alternative drives. From an environmental perspective, repairing vehicles which have already been produced is likewise a useful option – after all, this saves the most resources. This particularly applies to the increasingly complex and precise fuel system on a car. Here ultimately, fuel can only be reliably supplied, precisely dosed and optimally combusted under the condition that the individual components are fully functioning. From the perspective of performance and avoidance of emissions, damage should therefore be quickly repaired.

In this regard, MS Motorservice International GmbH offers a comprehensive portfolio of high-quality repair solutions. The expert for spare parts in OEM quality provides fuel pumps, pump modules, sender units, system-pressure regulators, non-return valves, regeneration valves and canister purge valves from the Pierburg brand to the aftermarket. Pierburg fuel pumps, for example, have met the high quality standards of vehicle manufacturers for many decades. Motorservice has approximately 400 of these fuel pumps and fuel delivery modules – which are used in almost every make of vehicle – in its product range.

Well-thought-out solutions
Many of these products were developed towards having the highest possible durability, reliable functionality and fast and simple replacement in the event of damage. For example, if the fuel delivery module fails, the cause is often the fuel pump itself. Attachments such as the fluid-level sensor, flange cover or swirl pot are usually not affected. This is why Motorservice offers a range of spare pumps, where only the fuel pump itself has to be replaced and not the complete fuel delivery module. With the corresponding fitting tool (item no.: 12 00005 14 004) for these fuel pumps, the company supplies the right auxiliaries for reliable and quick repair as well.

Helpful special tools
However, there may be various causes for malfunctions in the fuel supply area. This is why experts initially recommend checking the fuel pressure and fuel flow. Motorservice has assembled a test kit (item no.: 12 00003 14 900) especially for this purpose; it allows the flow rate to be measured without necessitating removal of the fuel pump. Be it blocked fuel filters, fuel filter sieves or lines, faulty fuel pressure regulators, fuel pumps or fuel non-return valves, leaking fuel in-tank modules or much more, the fuel pressure test kit makes inspection a great deal easier for the repair shop. In the case of damage to the fuel lines, there is likewise a suitable repair kit (item no.: 12 00002 14 900) for this available from the spare parts expert. It has the most common connections for fuel filters, fuel pump connectors and fuel pumps, as well as pipe sections and pipe connectors, including refill packages. 

Demand based and gentle
Motorservice also provides the aftermarket with suitable control units for fuel pumps for modern engine management systems. In the case of an unregulated fuel supply without control units, the fuel pump always delivers at maximum performance in the fuel tank. As a result, excess fuel flows back into the fuel tank via the return line. With regulated fuel supply on the other hand, the fuel pump is triggered by the fuel pump control unit with a pulse width modulation signal (PWM signal). Thus, demand-based fuel feed, with its significantly lower energy consumption, is a development which further enhances the efficiency of modern engines.

About Motorservice
As a sales organisation for Rheinmetall Automotive's aftermarket activities, Motorservice acquires a large proportion of its range internally from within the group, including the subsidiaries Kolbenschmidt and Pierburg. The internationally active spare parts specialist also has the know-how of a large international automotive supplier. Customers therefore benefit from products in OE quality.
